ESA Voyage 2050 white paper -- Faint objects in motion: the new frontier of high precision astrometry
F. Malbet, U. Abbas, J. Alves +28
Sky survey telescopes and powerful targeted telescopes play complementary roles in astronomy. In order to investigate the nature and characteristics of the motions of very faint ob…
Origin of Giant Stellar Clumps in High-Redshift Galaxies
Xi Meng, Oleg Y. Gnedin
We examine the nature of kpc-scale clumps seen in high-redshift galaxies using a suite of cosmological simulations of galaxy formation. We identify rest-frame UV clumps in mock HST…
Formation and evolution of globular clusters in cosmological simulations
Hui Li, Oleg Gnedin
In a series of three papers, we introduced a novel cluster formation model that describes the formation, growth, and disruption of star clusters in high-resolution cosmological sim…
High Resolution Optical Spectroscopy of Stars in the Sylgr Stellar Stream
Ian U. Roederer, Oleg Y. Gnedin
We observe two metal-poor main sequence stars that are members of the recently-discovered Sylgr stellar stream. We present radial velocities, stellar parameters, and abundances for…
Disruption of giant molecular clouds and formation of bound star clusters under the influence of momentum stellar feedback
Hui Li, Mark Vogelsberger, Federico Marinacci +1
Energetic feedback from star clusters plays a pivotal role in shaping the dynamical evolution of giant molecular clouds (GMCs). To study the effects of stellar feedback on the star…
Origins of scaling relations of globular cluster systems
Nick Choksi, Oleg Y. Gnedin
Globular cluster (GC) systems demonstrate tight scaling relations with the properties of their host galaxies. In previous work, we developed an analytic model for GC formation in a…
